A press release signed by Kelly said Harmon “has elected to pursue other opportunities where she can best use her talents.”

Harmon was at the helm of the chamber during the problem-plagued 2013 Taste of Lone Tree. The well-attended two-day event suffered from a downturn in restaurant participants; inadequate staffing, food and alcohol; and muddy, rain-soaked grounds that delayed its Aug. 11 opening. Some local business owners and participants sharply criticized the event, prompting the chamber to host a debriefing session with them.

Chamber officials have not yet said whether the event, which had been held annually for six years, will continue.

The chamber’s release thanked Harmon for helping rebrand the chamber’s logo, reorganize the office and boost membership, but continued: “As with any organization’s evolution and our desire to grow services to our membership, priorities shift.”

Harmon helped create a Healthcare Commission and coordinated a June panel discussion in Lone Tree on changes in national health care. She had planned to create more such groups, and cited among her goals with the chamber “to be more of service to the community, both the business and residential community.”

She was a former marketing and public relations director for the Denver/Boulder Better Business Bureau.

The chamber release said the board has assembled a team to lead the search for a new director, and hopes to have a new person on board quickly.

“We are proud of our many accomplishments over the past several years and look forward to many more going forward,” it read.

Harmon replaced former chamber director Michelle Holbrook, who resigned in late 2012 to become the director of Denver’s Christian Youth Theater. The Lone Tree Chamber was established in 2006; Holbrook was its first paid director.
